Original story (March 6, 2014): As we all know — much as we may hate to remember — this season of Grey's Anatomy is Sandra Oh's last. But now we know one way in which Shonda & Co. are paying tribute to her character, Cristina Yang.

TVLinereports that Season 10, Episode 17 — "Do You Know?" airing March 27 — will "find Cristina imagining the different routes her life could take via a Sliding Doors concept."

In case you're not a fan of Gwyneth Paltrow rom-coms, Sliding Doors was a 1998 film that shows the two ways a London woman's love life could go based on whether or not she caught a pivotal train.

We first knew that this installment would explore hypotheticals back in January, when editor David Greenspan tweeted that it'd show a "what-if scenario."

Update (March 12, 2014): Kevin McKidd (Owen Hunt) tells TV Guide that it's a patient who inspires Cristina's mindquest — and that all of the futures she imagines will loop back to him. "A patient makes Cristina's character [think about] possible scenarios of where they're going to end up because they keep coming back to each other," he teases. Consider us hooked!
